Utility Model Essence

The stamp for separating operations contains the upper fixed plate 1 (Fig. 1, 2, 5) fixed to the slider 2 (Fig. 1, 2, 5) of the crank press (Fig. 1) and the lower fixed plate 3 (Fig. 1, 2 , 4, 5). The stamp is equipped with a guiding device 4 (Fig. 1, 2, 4) mounted to the end of the lower fixed plate 3 (Fig. 1, 2, 4, 5) and a pneumatic cylinder 5 (Fig. 1, 2). Guide rails 6 are mounted on the lower surface of the upper fixed plate 1 (Figs. 1, 2, 5) and the upper surface of the lower fixed plate 3 (Figs. 1, 2, 4, 5). The stamp contains an upper movable plate 7 (Figs. 1-3, 5) and a lower movable plate 8 (Figs. 1-3, 5), interconnected by columns 9 (Figs. 1-3, 5) and forming a movable carriage 10 ( 1-3, 5), symmetrically located relative to the longitudinal axis of the stamp and having wheels 11 (Figs. 1-3, 5) installed in the guide rails 6 (Fig. 5). On the upper movable plate 7 (Figs. 1-3, 5) of the movable carriage 10 (Figs. 1-3, 5), a punch holder 12 (Fig. 5) is mounted on which the punch 13 is mounted (Fig. 5), and on the lower movable the plate of the movable carriage 10 (figures 1-3, 5) are fixed matrix holder 14 (figure 5) with the matrix 15 (figure 4, 5). The movable carriage 10 (Figs. 1-3, 5) is made with the possibility of horizontal movement along the guide rails 6 (Fig. 5) in the technological process of separating operations, mainly of the tape blank and with the possibility of returning to its original position by means of a pneumatic cylinder 5 (Fig. 1, 2). The stamp is equipped with an electronic device 16 (Fig. 1, 2), configured to synchronously move the tape billet and moving with the mobile carriage 10 (Figs. 1-3, 5) of the matrix 15 (Figs. 4, 5), with the time of cutting the workpiece with a punch 13 (figure 5) and return it to its original position. To enable emergency stop line profiling in the case of continued movement of the movable carriage 10 (Fig.1-3, 5) after a signal from the pneumatic cylinder 5 (Fig.1, 2), the stamp is equipped with a limit switch 17 (Fig.1, 2) installed on the lower fixed plate 3 (Figs. 1, 2, 4, 5) of the stamp and the movable carriage 10 (Figs. 1-3, 5) fixed on the lower movable plate 8 (Figs. 1-3, 5), Limit switch 17 ( figure 1, 2) is made with the possibility of its operation and emergency stop line profiling in the case of continued movement of the mobile carriages and 10 (Figures 1-3, 5) after receiving the signal from the pneumatic cylinder 5 (1, 2).

The guide device 4 (FIGS. 1, 2, 4) of the stamp serves to center the workpieces, including the metal tape, and is equipped with adjustable base elements made in the form of longitudinal, parallel to the table guide rails 18 (FIG. 4), fixed with screws 19 ( figure 4) mounted on the lower fixed plate 3 (figure 4) with the possibility of changing their width.

The stamp works as follows.

The workpiece, including sheet metal tape, is centered on the guiding device 4. The centered workpiece from the guiding device 4 enters the working area of the stamp in the movable carriage 10. When a signal from the pneumatic cylinder 5 enters the pneumatic system of the crank press, the slider 2 of the press is lowered and the separation is performed operation. In this case, the punch 13 is in the matrix 15, the movable carriage 10 moves together with the profile tape due to the drive of the roll forming mill (not shown in the drawing). The forward movement of the mobile carriage 10 of the stamp occurs until the signal arrives in the pneumatic system, followed by the opening of the punch 13 and the matrix 15 of the stamp. After raising the press slider 2, the solenoid valve (not shown in the drawing) returns the movable carriage 10 all the way to its original position. The limit switch 17 controls the extremely permissible position of the mobile carriage 10. In the event that, upon receipt of a signal, the mobile carriage 10 has not stopped and continues to move forward, the limit switch 17 is activated and the entire profiling line is stopped.

The stamp is designed to work as part of a line for profiling a metal strip from a flat workpiece into a section of a given shape. The stamp refers to the technological equipment for separating operations (cutting, punching, cutting, perforation) of sheet metal with a certain step without stopping the profiling line.
